I'm trying to find a my XML file called ClassData.xml, but can't find it. The file itself is hidden in a folder called Data. I don't know how to get to the directory of my project where the file is. I'm using ios simulator.

I am trying to change the code so the login screen is the rootViewController but when I remove the rootViewController from the tabController assignment I get an error that casting a UITableViewController to UITabBarController always fails. Does anyone know why casting a UITableViewController to a UITabBarController always fails unless the UITableViewController is the rootViewController? Is there a way to change the launch screen to a different controller without changing the rootViewController assignment? Here is the storyboard for visual:

I am working on an app in angular 4 and deploying it on Ipads using Cordova. When I run the application in any browser the styles attached "input:focus" are applied and is working fine.
When I run the cordova build and execute in Ipads using XCode, the styles are not applied. Please let me know if anyone has any solution to solve the issue.
CSS I used is very simple and copied below

I am building a website that basically chooses a random city (within my custom array) and displays the top 20 events (ticketmaster api) and top hotels (Google Maps Place Autocomplete Hotel Search) for that city. The problem I am having is with the Place Autocomplete Hotel Search. For those unfamiliar, check out an example of the functionality within Google's documentation here.

I'm able to populate the input field with a random city name, but am unable to get the field to submit. Essentially, I want the user to press a 'GO' button on the screen which would trigger an event of randomly choosing a city from my array, and filling/submitting that autocomplete input field behind the scenes...without the user having to type into an input field and press Submit (don't know if that's possible).

Here's what I have so far, but I'm a beginner coder and could be way off...what I have doesn't work. I tried .click(function() {}) but that didn't work either.

I would like to use google maps for a SaaS product we are developing for one of our clients.
